FILLING-FEEDER FOR FlLLING-BEPLENISHING LOOlVlS.

SPECIFICATION forming part of Letters Patent No. 769,573, dated September 6, 1904.

Application filed June 8, 1904. Serial No. 211,581. (No model.)

To all who! it may concern:

Be it known that l, ED\\'ARD S. STIMPSON, a citizen of the United States, and a resident of Hopedale, county of \Vorcester, State of Massachusetts, have invented an Improvement in Filling Feeders for Filling Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the draw- I ings representing like parts.

In United States Patent No. 755,252, granted to me March 22, 1901, l have shown an improved and novel construction of fillingfeeder for automatic looms of the Northrop 5 type, the feeder being arranged for either bobbins or cop-skewers and having tip-holders of such construction that they are retained in position without the use of screws or other fasteners.

My present invention has for its object an improvement upon such apparatus whereby at the time of transfer the movement of the filling-carrier from the feeder causes a partial unwinding of the filling therefrom, due to the 5 way in which the filling end is guided and held, so that a slack portion is provided suflicient to obviate filling breakage when the shuttle is picked after transfer. The formation of such a slack portion is secured in my 3 present invention without the addition of any separate movable parts, but is attained by a change in the construction of the tip-holder, as will be fully described hereinafter.

Figure 1 is a front elevation and partial section of the replenishing mechanism of a loom of the Northrop type and with a fillingfeeder embodying one form of my present invention, the section being taken on the line 1 1, Fig. 2. Fig. 2 is a partial inner side ele- 4 vation of the end or plate of the feeder which supports the tips of the filling-carriers, the latter being shown in cross-section on the line 2 2, Fig. 1. Fig. 3 is an enlarged face view of one of the tip-holders made in accordance with my present invention, and Fig. 4: is a detail top or plan view of a portion of the feeder to show the diagonally-placed guide-head located between the outer end of the feeder and the tilling-end-holding plate.

Referring to Fig. 1, the feeder-plates a a, having their hubs u (.1 connected and rotatably mounted on a stud u", secured to the stand A the filling-end holder 1/, rotatable with the feeder, the transferrer f, and its tip-depress ing arm 21 maybe and are substantially as in United States Patent No. 529,910 and operate as therein set forth, the filling-feeder being intermittingly rotated in any suitable manner, the holder 1/ having its periphery notched at 7F, as usual, and provided with a central stud 6o 7) The plate a has the usual peripherallyarranged pockets to receive the heads of the filling-carriers, and the radial openings 4"" in the plate a, the annular lip or rib a" on the outer side of the plate, the spring-seats a spanning the openings and socketed on their inner faces at 5 to receive the coiled springs s and the tip-holders mounted on the plate a" are all substantially as in my PatentNo. 755,252 referred to. As clearly shown in Fig. 3, the elongated body if of the tipholder is transversely grooved at its inner end at 7i to receive and rock on the flange a, and the thickened portion 71"" at the outer end or head of the tip-holder forms a U-shaped seat 7 5 h for the blunt tip of a bobbin, with a longitudinal narrow seat 72F to receive the sharper tip of a cop-skewer, the springs s" pressing against the backs of the tip-holders, all as in my said patent. l have shown cop-skewers O in Figs. 1 and 2, two being shown in the former figure, the lower one being in position to be transferred to the shuttle. in my patent the head of the tip-holder is provided with like lateral ears 12 to rest upon the plate a at each side of one of the openings 1/ therein; but in my present inventionl displace one of said ears /1 by a wider ear or extension a having a deep notch or groove if in its outer transverse edge to support and guide the lill- 9o ing end. This extension 71 however, cooperates with the plate a in a manner similar to the ear /1, as shown clearly in Fig. 2. The filling-end support A is located at that side of the tip-holder adjacent that side of the filling-carrier held thereby from which the filling unwinds, as will be clearly understood from Fig. 2. Remembering that in said Fig. 2 the inner face of the plate a is viewed, it will be seen that in unwinding the filling 26 turns in the direction of the arrow 10, or from right to left, and the filling-end support 72 is accordingly at the right-hand side of the tipholder. In other words, as the feeder rotates in the direction of arrow 15, Fig. 2, the extensions [L8 are at the leading sides of the tipholders. The filling end is led from the fillingcarrier to one side into the groove h and thence diagonally to a notch Z2 in the fillingend holder 6, and, finally, it is wrapped around the stud 6 as shown in Fig. 1, the diagonal direction of the thread t being adapted to facilitate the positioning of the same for threading when its filling-carrier is inserted in the shuttle.

Referring now to Fig. 2, it will be seen that when the lowermost filling-carrier is transferred it will move from full to dotted-line position, and in so doing the thread will be unwound for a part of a turn, owing to the fact that it is supported by the tip-holder at the adjacent side, and this partial unwinding gives up or forms a slack portion of the thread sufficient to prevent breakage when the shuttle is thrown from the replenishing shuttle-boX. If the thread were supported by the tip-holder at the other or left-hand side, viewing Fig. 2, it will be manifest that upon transfer there would be a partial winding of the thread upon the filling-carrier, tightening instead of slackening the thread. The slackening of the thread, it will be observed, is attained by or through the manner in which the thread is supported by the tip-holder and in a very simple and effective way without any additional parts or moving members.

In order to assist the attendant in placing the filling ends in the proper notches of the filling-end holder 6', I have extended the stud f, on which the transferrer rocks, and secure thereto an arm g, having a diagonal head g interposed between the holder 6 and the outer end plate a of the feeder. (See Figs. 1 and 4:.) This head has the proper direction for the filling ends, and as the attendant places the filling-carriers in position he leads the filling ends over parallel to the guide-head g I have broken out the stud f in Fig. 1 between the arm 9 and the transferrer-spring S to show more clearly the tip-holder at the bottom of the feeder.

In Fig. 1 the usual winding is shownthat is, from right to left, viewing the fillingcarrier from the tip end thereofso that the unwinding is in the reverse direction, and the slackening is effected at the time of transfer, as hereinbefore described.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A filling-feeder adapted to sustain a series of filling-carriers, a transferrer to remove the latter one by one, and means to cause a partial unwinding of filling from a filling-carrier at time of its transfer, to provide a slack portion of the filling.

2. A filling-feeder adapted to sustain a series of filling-carriers, a transferrer to remove the latter one by one, and individual means located near the tips of the filling-carriers to cause a partial unwinding of filling from each filling-carrier as it is transferred, to thereby provide a slack portion of the filling.

3. A filling-feeder comprising a plate adapted to sustain the heads of a circularly-arranged series of bobbins or cop-skewers, a parallel and connected plate, individual means carried by the latter to cause a partial unwinding of filling from each bobbin or copskewer at time of transfer thereof, and a transferrer to effect such transfer.

4.. A filling-feeder comprising a plate adapted to sustain the heads of a circularly-arranged series of bobbins or cop-skewers, a parallel and connected plate, a series of yieldingly-supported' holders thereon adapted to receive and hold the tips of bobbins or copskewers, means on each tip-holder to engage the filling end leading from the adjacent bobbin or cop-skewer, to cause a partial unwinding of filling therefrom at the time of its transfer, and a transferrer.

5. A filling-feeder comprising a plate adapted to sustain the heads of a circularly-arranged series of bobbins or cop-skewers, a parallel and connected plate, a series of yieldingly-supported holders thereon adapted to receive and hold the tips of bobbins or copskewers, means located at the outer end of and movable with the feeder, to position and hold the filling ends, a device on each tipholder to engage the filling end leading from the adjacent bobbin or cop-skewer and cause a partial unwinding of filling therefrom at the time of its transfer, and a transferrer.

6. A filling-feeder comprising a plate adapted to sustain the heads of a circularly-arranged series of bobbins or cop-skewers, a parallel and connected plate, a series of yieldingly-supported holders thereon adapted to receive and hold the tips of bobbins or copskewers, means located at the outer end of and movable with the feeder, to position and hold the filling ends, a lateral extension on the outer end of each tip-holder at the leading side thereof to engage the filling end leading from the adjacent bobbin or cop-skewer and cause partial unwinding of the filling therefrom at the time of its transfer, and a transferrer.

7 A rotatable filling feeder comprising connected plates to support the heads and tips of a circularly-arranged series of filling-carriers, a peripherally-notched plate having a central holding-stud, mounted on the outer end of and to rotate with the feeder, to direct and hold taut the filling ends, and a fixedlymounted guide between the outer plate of the feeder and the notched plate, to indicate the direction of the filling end when a filling-carrier is inserted in the feeder.

8. A filling-feeder adapted to sustain a circularly-arranged series of filling-carriers, means at the outer end of and rotatable with the feeder to hold the filling ends led from the tips of the filling-carriers, a transferrer to remove the latter one by one from the feeder, and a guide-support for each filling end beyond the tip and adjacent the' side of the filling-carrier from which the filling unwinds, to provide a slack portion of filling at the time of transfer of its filling-carrier.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
